Summer Berry Poke Cake (Printable)

Moist vanilla cake infused with berry sauce and topped with whipped cream. A refreshing summer dessert perfect for outdoor gatherings.

# What You Need:

→ Cake Base

01 - 1 box (15.25 oz) vanilla or white cake mix with required eggs, oil, and water

→ Berry Sauce

02 - 2 cups mixed summer berries (strawberries, blueberries, raspberries, blackberries)
03 - 1/2 cup granulated sugar
04 - 1/2 cup water
05 - 2 tablespoons lemon juice
06 - 2 tablespoons cornstarch

→ Whipped Topping

07 - 2 cups heavy whipping cream
08 - 1/4 cup powdered sugar
09 - 1 teaspoon vanilla extract
10 - 1 cup fresh mixed berries for garnish
11 - Fresh mint leaves (optional)

# Steps:

01 - Prepare cake batter according to package directions and bake in a 9x13-inch baking dish. Allow to cool for 15 minutes before proceeding.
02 - Using the handle of a wooden spoon, poke holes evenly across the entire cake surface, spacing approximately 1 inch apart.
03 - Combine mixed berries, granulated sugar, water, and lemon juice in a saucepan over medium heat. Bring to a gentle simmer. Whisk cornstarch with 2 tablespoons cold water, then stir into berry mixture. Cook for 2-3 minutes while stirring constantly until sauce thickens.
04 - For a smoother consistency, press berry sauce through a fine-mesh sieve to remove seeds. Pour warm sauce evenly over the cake, ensuring it fills the poke holes completely.
05 - Allow cake to cool completely at room temperature, then refrigerate for at least 1 hour to let flavors meld and set.
06 - Beat heavy whipping cream with powdered sugar and vanilla extract using an electric mixer until stiff peaks form.
07 - Spread whipped cream evenly over the chilled cake surface. Top with fresh mixed berries and mint leaves just before serving.

# Expert Advice:

01 -
  • The cake stays impossibly moist because the berry mixture seeps into every single nook and cranny, creating pockets of fruit filled magic in each bite
  • Its the make ahead dessert that actually gets better after sitting in the fridge, letting all those summer berry flavors deepen and mingle
  • You can absolutely use a box mix without anyone guessing, because the homemade berry sauce and fresh whipped topping make it taste completely from scratch
02 -
  • The cornstarch mixture must be whisked with cold water before adding to hot sauce, or it will turn into lumpy little clumps that refuse to dissolve no matter how much you stir
  • Make sure your heavy whipping cream is thoroughly chilled before whipping, because warm cream simply will not hold those beautiful stiff peaks you need
  • If youre making this ahead, add the fresh berry garnish right before serving, because the berries will weep and make your whipped topping look sad after sitting too long
03 -
  • Room temperature eggs and oil create a more even textured cake, so set those out while you preheat the oven
  • If your whipped cream feels too soft, add another teaspoon of powdered sugar and keep whipping, but be careful not to overbeat or it will turn into butter
